The next day, the women of the Normandy woke up fully rested, not only physically, but mentally as well - as if the time spent fucking together healed their bodies, minds, and souls. Talking and joking, they dressed up and returned to the ship, meeting their male companions there. Few of them commented on how radiant the girls looked and they thanked them for that, but without any discussion about the reason for it.
But soon they all became serious, as a shore leave came to an end and they were in the war again - first, they attacked Cerberus in their headquarters, and next the whole Citadel fleet made a final assault on Reaper forces on Earth. During both those campaigns, the women of the Normandy drew strength from their friendship, fighting like lionesses and being crucial in reaching success.
The second win was obtained especially hard, as when the ground forces failed to reach Reapers' transporting beam, Shepard found herself alone on the ruined Citadel. After a battle with Marauder Shields, confrontation with the Illusive Man, Anderson's death, and conversation with Catalyst, she had to make a choice for the entire galaxy.
Approaching the blue control panel, she was desperate to take control over Reapers for just a minute needed for her plan. But when she touched it, the ancient machines' shared consciousness almost completely dominated her own. She was about to lose the battle of wills, but then she saw all her female friends in her mind and she felt the strength of their friendship, even enhanced by their recent experience. That - and only that - gave her the power to push back, take control of the enemies, and fly them into the Sun, where they were finally destroyed for good.
The galaxy was saved that day and all its inhabitants could return to their own lives, including the Normandy crew. But the experience like the one the women of the staff lived through together had to leave a permanent mark on them - and it did.
Jane had a great time during the orgy, reconnecting with her bisexual side. Yet, when the excitement passed, she remembered that she not only cheated on Garrus but even called him during foreplay with her friends. Ridden with guilt, she confessed to him, but in return heard only the apologies for choosing the boys over her that night. "I'm the only one to blame," he said. "Besides, it had to be kinda hot." "It was," Shepard replied seductively. "Let me tell you how much." Then, she kissed him and next, they had one of the best sex in their lives. Since then, the tale of this wild night had become a frequent part of their foreplay.
Ashley remained mostly straight... mostly. Despite most of her serious relationships being with men, she wasn't shy to have frequent flings with women of all species. At the party, she tasted asari, quarian, and human juices, and soon she added also turian, salarian, drell, and even krogan tastes to her ever-growing collection of feminine flavors. And as a woman's juices taste almost as good licked from a cock as drunk directly from the source, she wasn't shy from doing threesomes as well.
For Tali, the sex during the orgy was the first in her life, making her acquainted with all forms of lesbian lovemaking: from licking to fingering, to tribbing, and finally to strap-oning. But, she also wanted to experience a real-life cock. Inspired by the biotic bubble that kept her safe back then, she came up with a similar yet technological solution which she made available for free to all the quarians out there, and the Fleet, once sexually suppressed, became much more liberal after that. Thanks to that, one lucky quarian named Kenn was the first to have heterosexual sex with Tali, in the threesome with another girl named Lia.
In Liara, the party was an awakening of her asari sexual nature and she definitively wanted more of that. Soon, the most successful - and prettiest - female agents of the Shadow Broker began receiving invitations to private parties all over the galaxy. Each of such parties was hosted by mysterious, masked asari, and many of them turned into lesbian orgies. When the rumors broke out, the performance of female agents increased, as everyone wanted to check if those rumors were true, only providing Liara with more opportunities to host those parties.
During the orgy, Miranda and Jack discovered that they were greatly compatible when it comes to sex. So they continued meeting up for booty calls every opportunity they had, practically looking for excuses to fuck. In time though they realized that it wasn't only sex, that they were quite similar to each other, and that they simply enjoyed spending time together. Finally, they decided to risk and officialy get together, what turned out to be the greatest decision of their lives.
